Oil Pressure Switch/Sensor on 1999 Chevrolet 1500 Pickup

Can anyone tell me where the Oil Pressure Switch/Sensor is located on a 99 Chevy K1500 5.0L/305.

your oil pressure switch is located right next to your dist.
Thanks, what a nightmare. I will need to remove everything off the top to get to it I guess. Does this take a special socket?
